The limited-government group said Wednesday it’s spending $1 million on an ad slamming Lt. Gov. David Dewhurst as moderate.

The 30-second television ad will run on broadcast and cable, according to the group, and a 15-second version will run statewide on conservative Web sites “as a component of an internet campaign designed to urge Texas Republicans to vote against Lt. Gov. David Dewhurst in the May 29th Republican primary.”

“Texans looking for a principled defender of economic freedom should vote for Ted Cruz in the Republican primary for U.S. Senate,” said Club for Growth President Chris Chocola.

“Moderate tax-raising David Dewhurst. Wrong for Texas. Vote against Dewhurst on May 29th,” says the ad.
Dewhurst has said he has “always opposed a business or personal income tax,” and he has worked to highlight his conservative credentials for this race.
